I would guess your fuel mileage will change.....several here in town done the 688 mod, and their mileage dropped into the 30's. Maybe you'll be lucky!!!!

I did encounter a small setback, namely that I am losing coolant somehow.
I will check the hoses and gaskets tomorrow. I think I'm losing it near the engine because I can smell the coolant burning away. This I think should be fairly easy to solve.
I'm curious to see if my mpg changes.
I've also got to check my air filter again, somehow I seem to have to keep the choke open slightly.
You'd think that with the 22 cent mod and the Hurricane mod she'd be getting enough gas.
Maybe with a bigger piston chamber I'll need more gas???
